h5 MediaRecorder 报错no mediarecorder handler can be created

Question

###
部分手机浏览器（UC、华为浏览器）var recorder = new window.MediaRecorder(stream);
报错信息：NotSupportedError: Failed to construct 'MediaRecorder': No MediaRecorder handler can be created

问题出现的环境背景及自己尝试过哪些方法

使用库：recorderRTc.js一样报错

相关代码

try {
            recorder = new window.MediaRecorder(stream);
            } catch (error) {
                 console.log('recorder is no suppose');
            }
